FC4 bus error message at boot time

[E GCP]

Hi,

Thanks in advance for any help.

I have an HP zd7000 running Fedora Core 4 with kernel-smp-2.6.14-1.1656_FC4. 
Every time it boots up it gives this error:

starting system message bus: unknown username "named" in message bus 
configuration file

The booting process finshes fine and I haven't found other problems, but I 
do not know what this error means and how to fix. I tried to google it, but 
I haven't been able to find something similar to it.

This is a clean installation of FC4. I installed it just recently over a 
newly formatted hard disk.

Thanks,
egcp
